The Sidney & Deanna Wolk Family Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- The foundation states that it does not accept unsolicited requests, so a cold application is not the route; a group would need to be invited, or reach it through an existing connection, and the filing says nothing more about how that happens.
- Its giving is spread across social services, elder care and education, with hospitals, youth and community, religious and arts organisations also in its record, so a group working in one of these fields may fit, though no detailed eligibility criteria are set out.
- Most of its grant dollars in its latest filing (99%) went to organisations it had funded in an earlier filing, so a new group should expect a field dominated by established recipients.
- About 8 in 10 of its grants fall between $5,000 and $160,000, with a median of $25,000, so a request in the low tens of thousands is typical, but its largest grant was $3,000,000, so that band is not a ceiling.
- The filings show grants mainly in Massachusetts, although no geographic focus is stated, so a group outside Massachusetts should not assume it is excluded or included on that basis.

Priority Areas

Its examples of significant recipients span elder-care organisations, education, food provision and agencies supporting people who are blind. The grant record also includes hospitals, youth and community organisations, religious institutions and arts organisations, alongside these examples.
